STOPPER-FASTENER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 442,940, dated December16, 1890.

Application filed August 21, 1890. Serial No. 862,581. (No model.)

To all whom it may concern.-

Be it known that I, JACOB S. BERGER, a citizen of the United States,residing at Brooklyn, Kings county, New York, have invented certain newand useful Improvements in Bottles; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and tothevletters of reference marked thereon, which form part of thisspecification.

My invention relates to bottles and similar vessels provided with a headadapted to receive a cork or stopper which closes the bottle; and itsnovelty consists in improved means employed to retain the cork in place,as hereinafter specifically described and claimed.

Figure l is a sectional view of a portion of a bottle closed with a corkand secured in place by my improved device. Fig. 2 is a perspective ofan emptybottle adapted to receive the cork, and Fig. 3 is a perspectiveView of the same with the cork and pins in place.

In the drawings, B is a bottle provided with a head N. This head nearits top is provided with two or more apertures H, which are cast orblown in the bottle in the course of manufacture or afterward drilled orbored therein.

C is the cork which should fill the interior of the head of the bottle,and which is forced into position in the usual manner.

P are pins or tacks provided with heads 1). These are made of suchlength that when forced diagonally downward through apertures H and intothe cork O they will not extend beyond the axis of the latter.

I am aware that pins have been passed horizontally through the head of abottle and through a cork therein. I also know that it has been proposedto pass a pin diagonally downward through the head and through or beyondthe axis of the cork. Further, I am aware, as illustrated in the patentof Bunting, No. 402,297, dated April 30, 1889,that a cover or cap for abottle has been provided with a stopper, the said stopper being securedin said cap by means of pins or tacks extending diagonallyinto the capand not beyond the axis of the stopper. In none of these devices,however, does the pressure on the interior of the bottle compress thecork in all directions against the sides of the bottle or object inwhich it is placed, and thus form a more nearly perfect barrier to theescape of gas from the bottle. In the case of Buntings stopper there isno more tendency to press the cork against the side of the bottle thanis present in the ordinary stopper without auxiliary fastening devices,because his fastening devices when in place are movable with respect tothe bottle. In order to secure the expansion of the cork within the neckof the bottle by the intern al pressure upon the cork, there must notonly be fastening devices not extending beyond the axis of the cork, butthese fastening devices must be connected rigidly to the bot tie and notto something independent of and movable with respect to the bottle. InBuntings device the cap which contains the stopper-fastening devices isnot a part of or fixed to the bottle, and hence when the cork is pressedupward the cap moves with it and the effect of expanding the cork byinternal pressure is absent.

hat I claim as new is- In combination with a bottle adapted to containaerated beverages and the like, the head of which bottle forms a fixedpart thereof and is pierced with holes extending diagonally downwardtoward the axis of the bottle, an expansible stopper in the head of saidbottle, and pins or tacks driven diagonally downward through said'holesand into the cork, but not beyond the axis of the latter, wherebypressure within the bottle may expand the cork in all directions againstthe neck of the bottle, substantially as described.
